PUDDLING-FURNACE.

Specification of Letters Patent.

Patented Jan. to, fair.

Application filed September 22, 1915. I Serial No. 51,999.

To all whom it may concern Be it known that I, EDWARD L. FORD, a citizenof the United States, residing at Youngstown, in the county of Mahoningand State of Ohio, have invented a new and useful ImprovementinPuddling-Furnaces, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in which- Figure 1 is a sectional elevationof a puddling furnace embodying my invention. Fig. 2 is an end view ofthe same, and Fig. 3 is an elevation of the detachable cover.

The present invention is an improvement upon the puddling furnacedescribed and claimed in my Patent No. 564,27 6 of July 21st, 1896.

One object of the present invention is to improve the door or cover atthe end of the furnace.

The furnace described in my said patent is provided with a plate or capmember carried by a burner and having its edges separated from the edgesof the furnace opening'sufiiciently to permit of the escape of theproducts of combustion.

The present invention is designed to provide a door or cover carried bythe furnace itself to rotate and move therein, but which is readilyremovable to permit of the discharge of the puddled ball. This door orcover is rovided with a central hole through which the fuel isintroduced and through which the waste gases also escape. The presentimprovement permits of the removal from the furnaces of a larger ballthan is possible in the old furnace, since in that construction if thedoor was made very large, the heat losses around its perimeter were sogreat that difficulty was experienced in keeping up the necessary heatin the furnace and an increased amount of fuel was required.

Another object of the present inventlon 1s to provide improved means forcarrying the load of the furnace when in its horizontal ballingposition, and which will automatically adjust itself to the varyingdiameter and angle of the axis of the furnace.

Referring to the accompanying drawlngs, in which I have shown apreferred embodiment of my invention, and which will now be described,the numeral 2 designates the furnace proper which is in general similarto that of my said patent.

3 designates the trunnions on which the furnace is journaled; and 4 thegearing for rotating the furnace about its own axis. Any suitable means,such as those shown in my previous patent, may be. employed for tippingthe furnace.

In accordance with my present invention, I make the opening 5 at the endof the furnace preferably of substantially the full internal diameter ofthe furnace body and normally close the same by means of a cover or doormember 6 which seats closely against the mouth of the opening. Thiscover or door member is formed with an approximately central opening 6through which the fuel is introduced by means of a suitable supply pipe7 and around the nozzle of which pipe the waste gases escape from thefurnace. Said member is rigidly secured to the furnace to rotate andmove therewith, but the securing means are of a readilyremovable'character so as to permit said member to be quickly detached.Any suitable fastenings may be employed for these purposes, such as theremovable keys 8.

It will be readily seen that the construction provides for the formationand removal of a puddled ball of maximum diameter While, at the sametime, there is very little opportunity for undue escape of heat from theinterior of the furnace.

In the operation of these furnaces, it has been found that great strainsare thrown upon the trunnions of the furnace during the ballingoperation, due to the fact that the furnace body or its supportingportion is not perfectly cylindrical and therefore does not perfectlyadapt itself to a fixed support such as has been heretofore employed,consequently, as the furnace is rotated, it is subjected to wabblingmovements of a nature to strain the furnace. To obviate this, I providea support which pref erably consists of the two rotatable wheels 9 journaled in a bracket 10 which is pivoted to a supporting member at 11and which member is in turn swiveled on a vertical axis 12 in thesupport 18.

14 designates a ring or track surrounding the furnace pot near its end.

It will be readily seen that by the combined action of the horizontalpivot at 11 and the vertical pivot 12, the supporting wheels willreadily adapt themselves to irregularities and variations in theposition of thefurnace as it is rotated during the balling operation. Inthis manner a constant support for the furnace is provided which greatlyrelievesthe trunnionsr I do not desire to limit myself to the particularembodiment of my invention which Ifhave herein shown and described, andit Will be obvious that various changes can be made in the details ofconstruction and arrangement of the various parts, thus the cover or topmember may be constructed and secured in different ays, the details ofthe universal support may be changed, and other changes may be made.

I claim:

1. A puddling furnace having one end permanently closedfand the otherend provided with a large opening, said furnace being carried bysupports which permit it to rotate and tip respectively on differentaxes, an annular cover detachably secured to the said open end androtating With said furnace, said cover acting to decrease the opening ofsaid end during the puddling operation, but which can be removed topermit of the removal of the finished puddle ball, and a fuel pipearranged to discharge fuel through the opening of said cover into thefurnace, the opening being arranged to allow the products of combustionto escape therethrough, substantially as described;

2. A puddling furnace having one end permanently closed and theother-end provided with a large opening, said furnace being carried bysupports which permit it to rotate and tip-respectively. on differentaxes, an annular cover detachably secured to the said open end androtating with said fur nace, said cover acting to decrease theopening'of said end during the puddling. operation, but Which can beremoved to permit of the removal of the finished puddle ball, and a pipeprojecting into the opening ofsaid cover and arranged to discharge fuelinto the furnace, the opening being arranged to allow the products ofcombustion to escape therethrough, substantially as described.

3. A rotary tipping puddling furnace, carried by supports which permitit to rotate and tip respectively on different axes, said furnace havingone end closed and the other end provided with a fuel inlet, an outletfor the products of combustion, and a single supporting structurearranged underneath the free end of the furnace, said support beingrotatable in a horizontal plane and having a plurality of supportingrollers, substantially as described.

4. A rotary tipping puddling furnace carried by supports which permit itto rotate and tip respectively on different axes, said furnace havingone end closed and the other end provided with a fuel inlet, an outletfor the products of combustion, and a single supporting structurearranged underneath the free end of the furnace, said support beingarranged to tilt in one plane and rotate in another plane and having aplurality of supporting rollers, substantially as described.

5. A rotary tipping puddling furnace carried by supports which permit itto rotate and tip respectively on different axes, said furnace havingone end closed and the other end provided with a. fuel inlet, an outletfor the products of combustion, and a single supporting structurearranged underneath the free end of the furnace, said support beingarranged to tilt in a vertical plane and having a plurality, ofsupporting rollers, substantially as described.

In testimony whereof, I have hereunto set my hand.
